JOHN A. MINSHULL, CLF WHITINSYILLE, MASSACHUSETTS, ASSIGNOR 10 WHITINMACHINE WORKS, 0F WHITINSVILLE, MASSACHUSETTS, A CORPORATION OFMASSACHUSETTS.

SPINNING, TWISTING, AND LIKE `IWACHINE` Application filed Jarmanr To @ZZ'1.0 tofr/L` t may concern Be it known that I, JOHN A. MINsI-IULL, acitizen of the United States, residing at lVhitinsville, in the countyof Worcester, Commonwealth of Massachusetts, have invented certain newand useful Improvements in Spinning, Twisting, and like VMachines, ofwhich the following is a specification, reference being had therein tothe accompanying drawings. Y The invention relates to improvements infoot boards of spinning, twisting and like machines, and the object ofthe invention is structed this is a tiresome operation espe-f cially tooperatives of medium height, and in order to make it easier for theoperative a stationary step is arranged on the floor alongside of the`machine, which answers the purpose but has the disadvantage of blockingthe working space between two adjacent machines. shown and describedherein, I eliminate this objectionable feature by providing a foot boardof suitable height from the floor that, when not in use swings up out ofthe way and when in this position its construction `serves as a guardpreventing damage to any of the projecting parts of the spindles andring rails that might otherwise be bumped and broken by trucks passing`through the space between adjacent machines.`

Referring to the drawings, which illustrate merely by way ofexample asuitable embodiment of my invention; Figure 1 is a perspective view of awell-known type of twisting machine showing my improvement in operativeposition thereon. Figure 2 is an enlarged sectional end elevation online 2-2 yof Figure 1, showing my im- In my improvements as 15, 1925.serial No. 21,562.

proved construction in operative position ir. full lines and in dottedlines its inoperative position. Figure 3 is a front `elevation of one ofthe foot board supporting arms and its hanger. Similar numerals refer tolike parts throughout the several views.

In the drawings, 10 and 11 are the head and foot ends respectively of acommon type of ring twisting machine, 12 is a stationary rail connectingthe two ends together. A plurality of L shaped hangers 13 are bolted tothis rail. On the lower end of cach hanger are stationed ears 14; and 15holding a stud or pivot 16 on which an arm 17 `is swingable. The footboard is held .in its horizontal operative position (see full lilies inFigure 2) by the side of the notch 19 on the arm 17 abutting against thelower end of the` hanger 13. Thestud 16 is provided with an enlarged end20 serving as a support for a coiled spring 21, one end 22 of which isfastened to the hanger 13 and the other end 23 abuts against theunderside of the foot board, the tension of all the springs togetherbeing sufficient to swing the foot board out of its operative position,whenever the operative steps from the board, into its inoperativeposition as shown in dotted lines in Figure 2.

By this `construction when the operative desires to attend to the creel24 he swings the foot vboard down to a position where he may easily stepup onto it and thus be in a' position where he may easily reach thecreel without undue exertion. After finishing his attentions' to thecreel he steps to the Hoor and the foot board automatically swings intoits inoperative position close to the side of the machine out of the wayof any operations along the side of the machine.

Underneath the `outer` side of the foot board 18 a rail 25 is fixedwhich serves to strengthen the board and also acts as a guard to preventtrucks, passing along the side of the machine, from hitting the ringrail 26 and the foot board supporting arms 17.

What I claim is:

1. In a machine of the character specified having a` rail connecting theend frames of the machine, a phirality of hangers in a stationaryrelation with said rail, a swingable arm pivoted to each hanger, a boarda stud supported by each pair of said ears7 an arin swingable on eachstud, a board supported by the arms, an abutment on each arm cooperatingwith the end of its supporting hanger, and a coiled spring mounted loneach stud having` one end iixed to the hanger and the other end abuttingagainst the underside of the arm whereby the resiliency of the springsoperate to swing the board from its operative position to its inioperative position against the side of the machine.

In a machine of the character specified having a rail connecting the endframes ot the machine, a. plurality of hangers fixed to said rail, aswingable arm pivoted to each hanger, a board supported by the arms,manually operated means to swing,` the board into a horizontallyoperative position and means to automatically swing the board from itsoperative position to an inoperative posi-- tion against the side of themachine.

4. In a machine of the character specified having a rail connecting theend frames oi" the machine, a plurality of hangers fixed 'to said rail,a swingable arm pivoted to cach hanger, a board supported by the armsadapted to assume a horizontal operative position under the influence ofthe weight ot' the operative, and means to automatically swing the boardfrom its operative position to an inoperative position on the removaloit the weight oi the operative.

In a machine of the character spccilied having a rail connecting the endframes oi the machine, a plurality of hangers in a stationary relationwith said rail, a swingable arm pivoted to each hanger, a boardsupported by the arms adapted to assume a horizontal operative positionunder the infiuence of the weight ci' the operative, a guard memberattached to the underside ot the board and means to automatically swingthe board from its operative position to an inoperative position againstthe side of the machine.

In testimony whereof, I have signed this specilication. Y
